SILO.

Specification of Letters Patent. Patented Jan, 23, 1,912,

` Application filed August 23, 1910. Serial No. 578,531.

To all 'whom 'it' may concern:

Be it known that I, OLIVER BRUMBAUGH, a citizen of 'the United States, residing at Louisville, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Silos; and I do hereby declare the following to be a full, clear, and exact description ofthe invention, suchas will enable others skilled in the art to' which it appertains to make and use the same.

My invention-relates to new and useful improvements in silos and similar construc- -tions, the walls of which are formed of plastic blocks or similar substances and my object is'to provide means for attaching door sections inposition in the opening in the wall of the silo.

, A further object is to so construct the meeting ends of thedoor sections as to cause the same to interlock with each other.

A further objectfis to provide recesses or seats in t-he blocks forming the door jamb, in which the door sections are adapted to fit, and, *a further object is to provide brace rods and extend the same across the door wayN or opening in the wall of the silo, whereby. the str1 ture wil-l be securely braced. te

Other objects and advantages will be hereinafter referred to and more particularly pointed out in the specification hereunto annexed.

. In the accompanying drawings which are made a part of this application, Figure 1 is a fragmentary elevation of a silo partly in section showing the manner ofapplying the doorsections and brace rods. Fig. 2 11s a4 vertical sectional view thereof.- Fig. 3 is a transverse sectionaljvlew.

' Referrmg to the drawings 1n which similar reference numerals designate correspond# -ing' parts throughout the several views, 1 indicates the wall of the silo, which is. preferably formed of blocks 2, said blocks being so, arranged that When. assembled, they will form preferably acircular structure in cross section and as structures of this kind are built to a considerable height, it is necessary to provide 'a door Way 3, which, in the present instance, extends from the bottom to the top of the structure.

The inner exposed cornersof the`blocks 2 forming the door jamb are provided .with angular recesses 4, into which are adapted to iit thev edges of door sections 5, the upper ends ofeach door section having a substan- -the projection 6 extends, thereby forming a close connection between the door sections. Each door section is preferably provided on its outer face with reinforcing strips 8, which extend vertically of the door sections and in order to -readily position the door sections within the door way or remove the same therefrom, handle bars 9 are extended transversely across the door sections and substantially at the longitudinal center thereof, theends of the handle bars being extended at right angles tothe trend of the bars and through the door sections, nuts 10 beingv attached to the inner ends thereof to hold the handle bars in position. By seating the edges of the door sections 'l in the recesses and providing the projections and grooves to receive the same at .the ends of the sections, the closure will be substantially V-sh'aped projection 6, while thellolwer l tially water and air tight, thereby preventl.

ingleakage of the contents of the silo and by applying the door sections in this manner, the -pressure'of the 4,contents ofthe silo will securely hold the door sections in position. As the omission of the blocks to formI the door way will necessarily weaken the wall at this point, I provide brace rods 11, which are extended transversely across the door vway at intervals and are projected through the ends of the blocks forming the door jamb, stripsbf wood 12 or other ma'- terial being extended vertically through the hollow blocks to receive the ends of the brace rods and by placing. nuts v1`3`on the ends of l the rods after they are introduced through the wall of the blocks and the strips will securely hold the rods in position. Instead, however, of extending the brace rods through the wall of the first block and through the vstrips adjacent the same, that form of red 14, shown in Fig. 4, may be used, which projects entirely through the first block and ceeding block, a nut 15v and washer 16 be ing engaged with the ends of the rod and a cushion 17 ,preferably of plastic material isv placed between the washer andjthe wall of the block, thereby preventing injury 4to the block by the washer coming in contact therewith. Thev brace rods-are placed in position at the time of building the structure, while the door sectionsare placed in the door Way, as the structure is being filled.

through the adjacent wall of the next sucl View of the simplicity of this device, theV structure may be Very cheaply constructed and at the same timev rendered extremely strong and durable. -It will further be understood, that although this construction'is adapted primarily to be used as a silo, yet grain and other substances may be stored therein, if desired.

What I claim is In a structure of the class described, the combination with a wall formed of hollow sections and having a portion of said sections omitted to form a doorway, the jambs of the doorway being formed solely by the hollow sections, the sections forming the door jambs having recesses in the inner exposed corners thereof, of brace rods extending transversely of the doorway and through thel ends of the sections forming the door jambs, said rods intersecting said sections substantially at their. transverse centers, stripsplaced end to end within the sections to either side of the doorway and extendlng the full height of said wall, the lowermost stripsv projecting below the doorway, the ends of said brace rods extending through the strips, means to hold the brace rods in engagement with the strips, a binding Vrod extending through the hollow sections forming the sill of the doorway and through the depending ends of the strips, door sectionsv having vtheir edges entered in the recesses inl the sections forming the jambs and means to interlock the meeting ends of the door sections.

In testimony whereof I have signed my name to thisspecication in the presence of two subscribing witnesses.

OLIVER BRUMBAUGH.
